The MB102 is a breadboard power supply module manufactured by the YwRobot Corporation in China. This module has the marking 545043 and MB V2 on the back of the printed circuit board (PCB). It provides dual 5 V and 3.3 V power rails, and has a multi-purpose female USB socket.


Breadboard from Jaycar – CAT.NO: PB8820

The AMS1117 is a voltage regulator manufactured by Advanced Monolithic Systems. There are two regulators where one regulator establishes a 3.3 V rail, whilst another establishes the 5 V rail.

The input voltage through the barrel socket must be between 6.5 V and 12 V. The maximum output current to be 700 mA.

The device provides voltage rails to both sides on the breadboard. The yellow jumpers are used to select the voltage levels desired 3.3 V or 5 V regulated)

There are also header pins for tapping off voltages, using a cable or jumper wires.

The green power LED is connected to the output rail.
